From: bh0139 on 21 Dec 2009 03:32 My laptop failed to power up . The green light at the power adapter is flickering. Is this a motherboard problem? If so, where do I get a repairer to rectify the fault. As the model is quite old (5 yrs old) , I do not intend to spend too much money on repair. Please advise. Darren
From: Barry Watzman on 21 Dec 2009 21:37 Almost certainly a bad motherboard (the motherboard has a switching power supply on it which is the likely source of the problem). If you can't replace the motherboard yourself, just sell the unit on E-Bay for parts. If you can repair it yourself, look for a motherboard or a unit with a good motherboard on E-Bay. The cost of a "new" motherboard would probably be over $300. The cost of having a repair shop change the motherboard is likely over $100. This type of repair can probably only be done economically if you can do it yourself, but if you can, you can likely find a replacement motherboard (which might be an entire computer, possibly with a broken LCD) for $50 or less. bh0139 wrote: > My laptop failed to power up .

You mean the box that has a cord that plugs into the AC and the other end to the laptop? If so, does it flicker if it is plugged into the AC and not into the laptop? If true, the AC adapter is bad. Most AC adapters don't even have a lite on them. So that is nice. If you mean the power lite on the laptop. Well that could be lots of things including the AC adapter. If it isn't the AC adapter, then it means something in the laptop is drawing too much power. The first thing to try is running it without the main battery. As when they start going bad, they draw more power which isn't really helping. As it just uses more current and only creates more heat. Which only makes everything worse. I'll stop here until you answer the above. Then we can go from there. -- Bill Gateway MX6124 ('06 era) - Windows XP SP2

It's times like this that my Kerio 'Enery Knight II' power adapter comes in very handy. The voltage output can be set to anything between 15V DC and 24V DC by swapping resistor modules and there are over half a dozen different tips with it so it fits most popular (older) laptops. It's 70W and I find it very handy. Especially when someone drops off a laptop for me to look at but forgets the adapter. -- Shaun. "Give a man a fire and he's warm for the day.

As I have a few of them myself. I never ran across one of the following, but wasn't there a manufacture like Dell or somebody that used a smart adapter? Thus it would send a signal to the laptop and the laptop refuses to power up unless it got the right code from the adapter. I am not sure if this was just a brief practice or not. -- Bill Gateway MX6124 ('06 era) - Windows XP SP2 |
